Hardware Installation Chapter 10
RADWIN 2000 User Manual Release 2.6.40 10-3
The other collocated radios in the site - the HSS Clients, are connected to the HSS Master and
synchronize their transmission to the pulses. An HSS Client can be configured to work in one
of two modes:
• HSS Client-Continue Transmission (HSC-CT): If the unit loses synchronization
with the HSS Master, the link remains active. However, without synchronization pulses,
it is possible that this unit will cause interference.
• HSS Client-Disable Transmission (HSC-DT): If the unit loses synchronization with
the HSS Master, the link is dropped until the synchronization pulses resume. This set-
ting prevents the unit from causing interference.
The remote ODUs that are not located at the hub site, are called Independent Units.
Hardware Installation
Connecting an HSS Unit
A single HSS unit supports up to ten collocated ODUs. In addition to each unit being con-
nected to its IDU or PoE device, the collocated unit has an additional cable that is connected
to the HSS Unit. The HSS Unit is a compact, weatherproof (IP67) connector box that is
installed on the same mast as the ODUs. All collocated units connect to this box using CAT-5e
cable. Cables in prepared lengths are available for purchase.
The HSS unit is supplied with ten protective covers; any port not in use must be closed with a
protective cover.
Note
WinLink 1000 radios used as independent units do not require HSS
hardware.
